What is the slot time?


#1

Looking at the blockchain explorer it looks like there are 3 slots every minute, e.g. slot times are 20 seconds. However the constants file specifies 15-second slot times.

What is the slot time? Why is the Github repo seemingly out of sync with the block explorer?


#2

20 seconds. Afaik, it is specified in the genesis block, as described here: https://github.com/input-output-hk/cardano-sl/blob/master/scripts/prepare-genesis/README.md

"slotDuration": "20000"
"slotDuration" - slot duration, in microseconds

Because your link is pointing to a commit from May 29, 2017 and to a file that does not even exist anymore :slight_smile:

Cardano’s mainnet was bootstrapped from the mainnet-genesis.json, which is in accord with the README that @vantuz-subhuman pointed out, and also the mainnet processing the slots in every 20secs. :slight_smile:
